Antwerp is the largest city in Belgium by area at 204.51 km2 (78.96 sq mi) and the capital of Antwerp Province in the Flemish Region. With a population of 530,504, it is the most populous municipality in Belgium, and with a metropolitan population of around 1,200,000 people, it is the second-largest metropolitan region in Belgium, second only to Brussels. Both economically and culturally, Antwerp is and has long been an important city in the Low Countries, especially before and during the Spanish Fury (1576) and throughout and after the subsequent Dutch Revolt. The Bourse of Antwerp, originally built in 1531 and re-built in 1872, was the world's first purpose-built commodity exchange. In 1920, the city hosted the Summer Olympics.
The inhabitants of Antwerp are nicknamed Sinjoren, after the Spanish honorific señor or French seigneur, "lord", referring to the Spanish noblemen who ruled the city in the 17th century. The city's population is very diverse, including about 180 nationalities; as of 2019, more than 50% of its population had a parent that was not a Belgian citizen at birth. A notable community is the Jewish one, as Antwerp is one of the only two cities in Europe (together with London and its Stamford Hill neighbourhood) that is home to a considerable Haredi population in the 21st century.
